We have made a major upgrade to new, faster, judging hardware. The time limits for all problems have been updated to reflect the new faster runtimes. Over the next weeks we will be rejudging old submissions and as a result you may see some of your old submissions suddenly become Accepted or, alas, stop being Accepted. The rejudgements of old submissions will tentatively be finished by March 2.
